mirroring all the comments about this _needing_ to be an extension..

in theory, one should be able to extract the "rule" definitions [1] and have it run with a conn str; instead of this _needing_ to be an extension.

in practice though, query plan analysis and missing indexes is a bigger use-case; since it's bad queries that take down the db.. and i see no rules here to help with that.
